Volatility Drought Persists Through OPEX

Line chart of SPX implied volatility term structure from Aug to Oct 2025 with teal line, purple shade, and labeled events.

SPX ended the week at a major SpotGamma support level of 6,450, driven by a combination of volatility compression, stabilizing dealer hedging flows, and the power of large options positioning. This week followed the trajectory outlined in our Founder’s Note on Monday morning: a benign CPI reading sent volatility even lower, and the SPX rose from 6,360 […]

Market Drifts Through “Death Valley” Vols

Line chart of SPX realized volatility with 1-month green and 3-month orange lines from 2024 to 2025 showing a large spike.

The S&P 500 delivered a week that looked dramatic at times, but ended up just drifting slightly — closing up 1.8% after a wild ride. While volatility spiked early in the week from tariff deadlines and semiconductor earnings disappointments, IV quickly collapsed as 0DTE flows reasserted control. This vol crush became a self-reinforcing tailwind for […]

SPX total gamma chart plots bars and a line versus strike prices, noting last close 6339, low volatility 6380 and high 6600.

What a difference a week makes. The S&P 500 went from consistently hitting all-time highs with 6,450 touched on Wednesday to close Friday down 1.6% to 6,238.This dramatic shift from “zombie market” to spiking realized volatility exemplifies the need for protective puts and/or VIX calls as insurance, as we highlighted in the daily pre-market Founder’s Notes throughout […]

Animal Spirits Roar as Market Catalysts Loom

Compass scatter chart plotting tickers by IV Rank and Risk Reversal Rank, yellow box on top-right quadrant.

This week delivered a fascinating mix of meme stock chaos, trade deal optimism, and mega tech earnings keeping traders on their toes despite unusually calm waters for the broader market. The S&P 500 ultimately gained ground, closing at all-time-highs, just below the pivotal SPX 6,400 gamma strike. Call option volumes exploded this week alongside broader […]

July OPEX Opens the Window of Weakness

This week delivered everything from mini-flash crashes to meme stock explosions, capped off with a July OPEX that reinforced our thesis about dangerously complacent volatility expectations. Our key levels proved their worth again this week: resistance at 6,325 limited upside attempts, and support zones at 6,250 and 6,200 provided reliable bounce points. The 6,200 pivot […]
